Early study shows cones in retinal degeneration, thought to be dormant, may retain visual function

“Dormant” cone photoreceptors continue to drive retinal activity for vision

“While the sensitivity of the cones was about 100-1000 fold less than normal, we were surprised to find that that the drop-off in sensitivity for the ganglion cells that project to the brain was much less,” said senior author Alapakkam Sampath. (Photo Credit: Miranda Scalabrino)
